Notes

This Web Data Connector only allows you to take single snapshots of data from
Facebook. You cannot use it to auto refresh on Tableau Server as this WDC only
stores short term access tokens. This is because the WDC only makes use of
JavaScript which is client based code and Facebook advise against asking for a
long term access token via client code.

For more information on this issue please see the Facebook documentation.
It is relatively simple to solve this problem using server based code such as
PHP, Python or NodeJS. We have no plans to extend this Web Data Connector to solve
this problem at this time.
